I have a 7206VXR that I'm using to terminate some PPPoE ADSL sessions. I have recently added another DS3+Serial interface to this unit for terminating some backhaul traffic from another carrier. The problem I'm having is that I'm intermittently loosing layer 2 on this link - although not completely.
When the failure occurs, my interface and line protocol show up/up. However CDPCP and IPCP show Closed.
Serial5/0 is up, line protocol is up
Hardware is M1T-T3+ pa
Internet address is x.x.199.1/30
MTU 4470 bytes, BW 44210 Kbit, DLY 200 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation PPP, LCP Open
Closed: CDPCP, IPCP, crc 16, loopback not set
If I bounce the interface by doing a shut/no shut, Layer 2 re-negotiates and ip connectivity returns.
The router is running aaa for my pppoe sessions, and I believe aaa is treating this new interface as a remote access link. Is there any way to exempt this interface from participating in aaa?
I believe aaa is causing the issue since the router "show aaa user all" shows a Unique ID for this connection and "show aaa sessions" shows a session ID for this link. When the circuit fails, both of these disappear.
I thought perhaps this was due to a timeout setting but I have been unable to determine what is causing IPCP to close. Any advice is appreciated.
